此活动的目的不是为了详细描述整个组织，而是只详细描述组织的某些部分就足够了，以使团队能够针对项目的剩余工作对要侧重的这些部分划分优先级。应根据进行业务建模的原因来决定工作的范围和详细程度（请参阅<a class="elementlinkwithtype" href="./../../rup_bm/guidances/concepts/scope_of_business_modeling_421E0509.html" guid="7.910331746816979E-305">Concept: 业务建模的范围</a>）。例如，业务流程重新设计（BPR）项目与域建模相比，需要范围更宽、更详细的业务模型。&nbsp;
</p>
<p>
    [<a class="elementlinkwithusertext" href="./../../rup/customcategories/references_56F06DFD.html" guid="7.755968586980351E-308">JAC94</a>]（第 164 页至第 167页）指出：“虽然我们认识到生成此模型是至关重要的，但我们要强调的是不要花费过多时间在上面，这点也很重要”。它还提到：“当然会存在有必要更详细地进行描述的情况，但这应该根据进一步建模所产生的负面后果来进行权衡”。之所以这样说，是因为在实践中往往是在方便的时候<b>而不是在必要的时候</b>结束建模。</p>
<p>
这通常是在先做了一些基础工作之后，再开始描述业务用例的。通常，会在必要时描述或优化组织结构（请参阅<a class="elementlink" href="./../../nup_base/workproducts/rup_business_architecture_document_patch_FFF763B3.html" guid="_hcjIMNYNEd255dRY2gdxDg">业务架构文档</a>的组织和地理视图）。如果将对大部分的业务进行建模，则可能会定义<a class="elementlinkwithusertext" href="./../../rup_bm/workproducts/rup_business_system_BB28EEB.html" guid="{4064F184-314B-4965-9F08-6AE5DBF6205A}">业务系统</a>。与之独立的是，第一张草图由<a class="elementlink" href="./../../nup_base/workproducts/rup_business_architecture_document_patch_FFF763B3.html" guid="_hcjIMNYNEd255dRY2gdxDg">业务架构文档</a>的域视图中的<a class="elementlinkwithusertext" href="./../../rup_bm/workproducts/rup_business_entity_638A1D00.html" guid="{9A14ED32-2AC5-457E-93B8-474642D33A50}">业务实体</a>组成。这在很大程度上通过提供讨论环境促进了业务建模研讨会期间的交流。并且，一个团队可能从<a class="elementlinkwithusertext" href="./../../rup_bm/workproducts/rup_business_worker_75AE475B.html" guid="{6C6AD4E6-C7B4-42E1-A3D1-FAC9DC2415B5}">业务工作者</a>开始，并且可能以他们在组织中的雇用职位作为起点。虽然业务工作者代表角色，因此就不应与职位混淆，但是职位可为确定业务工作者提供很好的起点。</p>
<p>
下一步将使用在评估业务状态期间已经确定的任何内容来定义<a class="elementlinkwithusertext" href="./../../rup_bm/workproducts/rup_business_goal_D99D08F9.html" guid="{6DC6732B-E7F1-495E-B5EC-AEBFD7BE80FE}">业务目标</a>。在描述业务目标期间或之后，将使用<a class="elementlinkwithusertext" href="./../../rup_bm/workproducts/rup_business_actor_25438422.html" guid="{EAD1B7E7-30C9-4494-B369-7F9E16A5329B}">业务参与者</a>和<a class="elementlinkwithusertext" href="./../../rup_bm/workproducts/rup_business_use_case_14F1BAF2.html" guid="{587A849E-B5F2-4B17-8C7F-1C59B0F5612D}">业务用例</a>（可能还有<a class="elementlinkwithusertext" href="./../../rup_bm/workproducts/rup_business_event_853992A0.html" guid="{EF5798CC-41AE-4137-B248-B308D465CF8A}">业务事件</a>）来填充<a class="elementlinkwithusertext" href="./../../rup_bm/workproducts/rup_business_use_case_model_EC79264C.html" guid="{89BEF367-5875-47E0-97D6-23E5BCCE52B8}">业务用例模型</a>。业务用例应往回跟踪它们所支持的业务目标。在跟踪期间，您可能会确定新的业务目标或优化现有业务目标。如果揭示了控制业务用例行为的需求（例如性能需求），则必须将它们记录到<a class="elementlinkwithusertext" href="./../../rup_bm/workproducts/rup_supplementary_business_specification_BBC64E05.html" guid="{0DADA95B-7C1D-44BD-9DB5-41AC99767753}">补充业务规约</a>中。
</p>
<p>
根据业务建模目标，将划分业务用例的优先级，并且<a class="elementlink" href="./../../nup_base/workproducts/rup_business_architecture_document_patch_FFF763B3.html" guid="_hcjIMNYNEd255dRY2gdxDg">业务架构文档</a>的业务进程视图将更新为对架构有重要意义的业务用例。然后，会为具有最高优先级的业务用例生成<a class="elementlinkwithusertext" href="./../../rup_bm/workproducts/rup_business_use_case_realization_55CAF00D.html" guid="{47F095EB-E651-4A34-B75B-BACE38ED90C7}">业务用例实现</a>。虽然将会优化已经确定的<a class="elementlinkwithusertext" href="./../../rup_bm/workproducts/rup_business_worker_75AE475B.html" guid="{6C6AD4E6-C7B4-42E1-A3D1-FAC9DC2415B5}">业务工作者</a>、<a class="elementlinkwithusertext" href="./../../rup_bm/workproducts/rup_business_entity_638A1D00.html" guid="{9A14ED32-2AC5-457E-93B8-474642D33A50}">业务实体</a>和<a class="elementlinkwithusertext" href="./../../rup_bm/workproducts/rup_business_event_853992A0.html" guid="{EF5798CC-41AE-4137-B248-B308D465CF8A}">业务事件</a>，但是可将它们用作起点。在描述这些当前业务用例实现时，将会揭示业务规则，这些业务规则应以文档形式或直接作为<a class="elementlink" href="./../../rup_bm/workproducts/rup_business_analysis_model_9449F63A.html" guid="{CF53445C-3351-46C6-810E-8251830029A7}">业务分析模型</a>中的元素记录到<a class="elementlinkwithusertext" href="./../../rup_bm/workproducts/rup_business_rule_9818835D.html" guid="{7F78B340-DD31-451A-9459-25F36E07401C}">业务规则</a>中。
</p>
<p>
在执行这些活动时发现的所有术语、概念和定义都必须记录到<a class="elementlink" href="./../../rup_bm/workproducts/rup_business_glossary_99F5CD1C.html" guid="{81F1291A-0FF1-492B-AD0C-10329B75A52F}">业务词汇表</a>中。在此活动结束时，必须在必要时根据通过具有最高优先级的业务用例获得的经验重新考虑并调整目标和期望。必要时，必须优化<a class="elementlink" href="./../../rup_bm/workproducts/rup_business_vision_55FFBD95.html" guid="{C1A31211-2C05-4665-8DC5-6BFB63F4FCE4}">业务愿景</a>。在执行此活动时，在评估业务状态期间作出的设想或决策是不正确的，这一点甚至可能变得很明显。如果是这种情况，则可能需要调整<a class="elementlink" href="./../../rup_bm/workproducts/rup_target_organization_assessment_850E5BD3.html" guid="{1C96F563-092E-4584-A1C9-1A8CF58C7FA6}">目标组织评估</a>以反映真实情况。
